Both sides agreed to the withdrawal of all foreign troops from Laos and Cambodia and the banning of bases and troop movements by these countries. It was agreed that the DMZ would remain a provisional demarcation line on the 17th parallel, with possible reunification of the country “by peaceful means”. An international monitoring commission of Canadians, Hungarians, Poles and Indonesians would be set up, with 1,160 inspectors overseeing the agreement. Under the agreement, South Vietnamese President Nguyen Van Thieu will remain in office until the elections. The North Vietnamese accepted the “right of the South Vietnamese people to self-determination” and stated that they did not inspire military movement throughout the DMZ and that there would be no use of force for the country`s reassurance. When the last convoy left, the prospects for peace and national reconciliation became real. Four parties to the conflict – the State of Cambodia (SOC) led by Prime Minister Hun Sen, The Khmer People`s National Liberation Front (KPNLF) led by Son Sann, FUNCINPEC under the leadership of Prince Norodom Rannariddh and khieu Samphan`s Khmer Rouge finally met in Paris and signed an agreement for “a comprehensive political settlement of the Cambodian conflict,” known as the , 1991. A tentative ceasefire agreement was reached in October 1972. The agreement called for the simultaneous withdrawal of American troops and the freedom of American prisoners of war, followed by a political solution for the future of South Vietnam.
Washington would expand economic aid after the war to help Vietnam rebuild its destroyed infrastructure. On October 22, Nixon suspended all bombing north of the 20th Parallel, and four days later Kissinger announced that “peace is within reach.” A few months after the International Conference on Kampuchea, convened by the General Assembly in New York from 13 to 17 July 1981, Secretary-General Javier Pe`rez de Cuellar renewed the offer of good services. He asked his Special Representative for Humanitarian Affairs in Southeast Asia, Rafeeuddin Ahmed, to establish contacts with the main countries concerned in order to assess the positions of the parties and to promote, through dialogue, the gradual reconciliation of positions. As a result, in February and March 1982, Mr. Ahmed undertook a mission to consult with governments in the region and to encourage them to consider convening a restricted international conference bringing together the parties concerned, the regions concerned and the five permanent members of the Security Council. At the same time, the Secretary-General continued his contacts with governments, both at UN Headquarters and in the capitals of the world. He told the General Assembly, at its 37th session in 1982, that only a comprehensive political solution, achieved through genuine negotiations, would ultimately bring peace. He reaffirmed his determination to continue to exercise his good offices and to help all parties involved find a negotiated solution.
On 23 October 1991, Cambodia and 18 other nations signed, in the presence of the UN Secretary-General, the agreements for the comprehensive political settlement of the conflict in Cambodia. The agreements were the culmination of more than a decade of negotiations in which the Secretary-General was closely involved from the outset.
